This invention relates to containers for fluidsgand more particularly to a container for a cleaning fluid, which container is adaptcdtocject a predetermined amount offluid on the surface to be cleaned. I This 'inventionhas particular application whenused-as a container for a cleaning liq- ..uid foryeye-glasses. In theprior art such -..flcleaning liquids have been deposited in bottles and when, required for use have been ejected throughaa small Yenturi meter, or what is commonly knownas an atomizer. "Such a de- -vice,while satisfactory after a fashion for use'in an eflice, cannot be transported, and .hasthe further disadvantage that the exact amount of liquidrequired cannot always be obtained-by ,pressure on the rubber bulb.

.Also the atomized liquidis not wholly de- .posited on the surface to be cleaned but is diffused through, the surrounding space. In another form of container, the liquidis forced .out through-a small opening'by means of viorlent shaking. Besides ruflling the temper of the user and .spattering-the liquid; everywhere but on the desired eye-glass,.thismethod very oftenresult-s in collision between the containing of either or both. r

In my invention, on the other hand, the

errand-the eye'- gla'ss,?with consequent breakother surface is obtained by a simple movement of the thumb. This movement deposits a drop of predetermined size on the surface reference to the accompanying drawings, in,

which Fig. 1 represents a'plan view of a container ding to my invention, with the cover partially in section; p Fig. 2 is a longitudinal section through the container;

Fig. 3 is an enlarged view showing the construction of the ejecting means;

exact amount to be deposited on the glass or 0 to be cleaned, and the container has the parspaced therefrom is ;a casing or envelope fl of hard rubber, metal or'similar material, which envelope has a tapered portion 5 to accommodate the tapered portion 3 of the soft rubbertube. A small length of glass tubing 7, is attached to the tapered portion 3.- The glass tubing 7may be straight or tapered, and may have either astraight bore or a spiral bore, or a plurality of such bores. Preferably I employ a piecev of tubing having a plurality ofspiral bores 6, as shown in i Fig. 5. These permit greater control over the amount of fluid to be ejected. Obviously,

5 the amount of fluid to be ejected may be varied by varying the size and number of bores in the glass tubing. The portion 5 of the envelope has a small o'pening'through which projects a button 8. c

The sides of the member 8 taper down- Wardly as shown in the figures to permit movement downwardly through the openmg 1I1 the portion 5 but not upwardly. This member 8 may be of hard rubber or metal of the same color to matclrthe envelopel l or may consist of soft rubber to permit a r bettergrip by thethumb. Underneath the member8 is attached, by cement or otherwise, a smallucushion 9. r This cushion 9 consists of soft rubber or similar material and is adapted to contact with the tapering por- .tion 3 of the soft rubber tube. [It desiredf members 8 and 9 constitute one piece,

1 as shown in Fig. 4.

It will be obvious that when liquid is con- I .tainedin the rubber tube 2, pressure of the thumb on the member 8 will compress the portion 3 of the soft rubber tube andeject a small amount of liquid through the,glass tip 7. The amountof liquid so ejected may be controlled. by. varying the thickness of the f cushion" 9, as well as by varying the glass tip 7. To prevent accidental pressure on the member 8 a locking means 12 may be provided to prevent downward movement of the member 8. This locking member 8 slides into position through a groove 25 in the easing 5.

o fill the receptacle 2 there is provided a long rod 13 which contacts with a lever 1 pivoted on a pin 15 in the casing t. When the lever 1 is turned the rod 13 will compress the soft rubber casing 2, thus creating a suction and permitting ingress oi the liquid through the tip 7. The lever 14 is so designed that it locks when in its normal position. If desired, the other end of the soft rubber tube 2 may be provided with an opening to permit insertion of the cleaning liquid. This opening may be closed by a corlr stopper 17. The sin'iilar end of the casing -i has an opening which is adapted to be closed by a screw member 18.

A-covcr i9 is provided to protect the glass tip 7 and tapered portion. 5 oi the cont...iner and has threads 22 to mate with the threads on the container. if desired, a clip 23 may be provided on the cover if) to pcrn'iit clamping in a pocket.

The operation of the device is as follows: To fill the container, the tip end T is ii'isertcd into the liquid and the lever it is turned so as to compress the soft. rubber tube. The atmosphere wil then force the cleaning liquid into the containing tube 2. If desired, the liquid may be inserted through the other end of the .tube alter cork member l? and the screw member 18 have been removed. When it is desiizd to deposit a drop of the cleaning fluid on the eye-glass the. thumb depresses the member 8 once and the exact amount comes out through the tip 7. It more liquid is necessary the member 8 is depressed again. It should be noted that the member 8 contacts with the tapered portion 3 so as to furnish a greater control over the amount of liquid to be ejected.

It will, therefore, be seen that with this device the required amount of fluid can be ejected when desired, and only when desired, with absolute safety to the article to be cleaned, to the container, and to surrounding obj eets and persons. The device is small, ad justable, transportable, and extremely etficacious tor the purposes desired.

This device may be used to contain perfume, oil, medicated liquids or other substances that can be made to flow under pressure and which are required in predetermined amounts.

The applicant does not wish to be limited to the exact structure or proportions shown in the figures, but is to be limited only as set forth in the following claims.

Claims:

1. A container for fluic s, comprising a soft rubber inner tube, a protecting outer casing,

means for ejecting a predetermined amount of the fluid from the inner tube, means for locking the ejecting means, and means for compressing the inner tube to permit ingress of the fluid.

2. A container for fluids, comprising a compressible inner tube tapered at one end, the tip ofthe tapered portion being open, a protecting outer casing similarly tapered, the tapered portion of the outer casing having a lateral opening therein, means projecting through this opening for ejecting the fluid from the tapered portion of the inner tube, and additional means for compressing the inner tube to permit ingress of the fluid through the same opening in the tapered portion of the inner tube. 1

3. A container for fluids, comprising a compressible tube, means for compressing the tube to eject fluid 'from one end thereof, means for com pressing the tube to inject fluid into the same end, and removable means at the other end of the tube for permitting ingress ot the fluid thereto or egress therefrom.

at. A container for fluids, comprising a compressible tube, a glass tip at one end of the tube, means forejecting a predetermined amount of fluid through the glass tip, means for injecting fluid through the glass tip, and a protecting cover for the glass tip.

5. A container for fluids, comprising a compressible inner tube tapered at one end, the end of thetapered portion being open, a glass tube attached to the open end, a protecting outer casing covering all portions of the compressible inner tube and a portion of ti. 3 glass tip, means for compressing the inner tube for injecting fluid into the inner tube through the glass tip, means for ejecting fluid from the inner tube through the glass tip, and removable means for covering the glass tip.
